An all-solid-state continuous-wave (CW) single-frequency 1.34 μm Nd:YVO4 laser is designed and fabricated. Based on a polarized and dual-end pumping scheme, a Nd:YVO4 crystal is directly pumped by an 880 nm laser diode, the 1.06 μm laser is suppressed by the coating of cavity mirrors, and a ring resonator is designed. The measured maximum output power of 9 W at 1.34 μm is obtained with optical-optical conversion efficiency of 18%. The stability of the output power is better than ±1% over a period of 4 h and the frequency shift is less than 8.5 MHz in 1 min. The output beam is almost diffraction limited with a measured beam quality of M2=1.03.
